Overwatch not accessing dGPU when Displaylink Hub plugged in

[AlbanRampon]

Hello,

Probably none of the options you listed.
If the only thing not working now is their app, then the issue is more likely to be the app...
The OS and drivers care about functionality and you report the system behaving correctly.
These apps should be non-essential for functionality (per Microsoft requirement) as the driver should be able to work without it.

What's most likely is that the app was conceived to report about directly connected displays and, wasn't conceived to have zero directly connected displays. Native support for DisplayLink USB indirect displays was introduced as standard in Windows 10 v1607.

Kind regards,
Alban
